Formula used
- Gross annual pay = annual salary + annual bonus.
- Total pre-tax deductions = retirement + health premiums + HSA + other pre-tax deductions.
- Federal taxable wages = gross annual pay − total pre-tax deductions.
- Federal taxable income = max(0, federal taxable wages − standard deduction).
- Federal income tax = progressive tax applied across filing-status brackets.
- FICA taxable wages = gross annual pay − health premiums − HSA contributions.
- Social Security tax = min(FICA wages, wage base) × 6.2%.
- Medicare tax = FICA wages × 1.45% + additional Medicare tax above the filing-status threshold.
- Estimated state and local taxes = taxable wages × selected flat rate.
- Net annual pay = gross annual pay − all deductions − all taxes.

FAQs
1. What does this calculator estimate?
It estimates U.S. gross pay, pre-tax deductions, payroll taxes, and take-home pay. It is designed for planning compensation, budgeting, and employee benefits discussions rather than replacing a production payroll system.
2. Why can net pay differ from a real paycheck?
Real payroll engines may use local rules, supplemental wage methods, year-to-date balances, tax credits, imputed income, garnishments, and employer-specific benefit treatment. This page intentionally simplifies several payroll details for flexible scenario testing.
3. Are state taxes exact here?
No. State and local taxes are modeled as flat user-entered percentages. Many jurisdictions use progressive rates, exemptions, special payroll formulas, or residence rules that can materially change actual withholding.
4. Does retirement always reduce Social Security and Medicare wages?
Not always. Traditional retirement plan deferrals often reduce federal taxable wages but still remain subject to FICA. This calculator keeps retirement separate from FICA wages to better mirror common payroll treatment.
5. How are health premiums and HSA contributions handled?
They are treated as pre-tax deductions that reduce federal, state, local, and FICA wages in this estimate. Actual treatment depends on how the employer plan is structured and administered.
6. Can I use this for offer comparisons?
Yes. Enter each offer’s salary, bonus, retirement savings rate, benefits cost, and estimated state taxes. Comparing net annual pay and net per pay period can make compensation packages easier to evaluate.
7. What is the employer contribution estimate?
It is a simple estimate of employer-paid retirement support based on the percentage you enter. It does not increase your take-home pay, but it helps show additional compensation value.
8. Can I download the results?
Yes. After calculating, use the CSV button for spreadsheet work or the PDF button for a clean summary report. Both export options are generated directly in the browser.
